<h3 id="rationale">Rationale:</h3>
<p><code>xargs -i</code> is a GNU specific option. It has been
deprecated in favor of the POSIX standard option <code>-I</code>.</p>
<p>Note that <code>-i</code> will implicitly use <code>{}</code> as a
token if nothing is specified, while <code>-I</code> requires it to be
explicit.</p>
<h3 id="exceptions">Exceptions:</h3>
<p>None.</p>
